MOUNTING BRACKET FOR ELECTRICAL BOX
FIELD OF THE INVENTION
[001] The present invention is a mounting bracket for an electrical box. In
particular, the
present invention relates to a mounting bracket for an electrical box that
provides additional
support when the bracket is mounted to a stud.

BACKGROUND OF INVENTION
[002] An electrical box provides an enclosure for an electrical receptacle as
well as a
termination point for wires carrying electrical current. Wiring entering an
electrical box is
typically connected to an electrical fixture or receptacle, such as a plug
outlet or switch. The box
can then be covered by a face plate having an opening, which allows access to
the outlet or
switch while preventing electrified components from being exposed. For most
applications, the
electrical box is surface mounted with the wiring to the box concealed in a
wall or ceiling. In
such applications, the electrical box is typically secured to a structural
member, such as a wall
stud or ceiling joist, in order to support the box. The support member must be
able to withstand
the forces exerted on the box and prevent movement of the box under situations
such as the
repeated insertion and removal of a plug or the operation of a switch.
Alternatively, electrical
boxes may be used in exposed-conduit wiring installations where they are
mounted to the
exterior of a wall, column or ceiling.

[003) In conventional construction, electrical boxes mounted within a wall are
typically secured
directly to studs either by screws or nails. The wall material, such as gypsum
board drywall, is
then installed on the studs to form the planar wall surface. In many
applications, including
interior walls of a structure, both sides of the studs are covered by wall
board. The studs can be
made of various materials including wood, steel and man-made composite
materials. Wooden
studs are traditionally used in residential construction and steel studs are
commonly used in the
construction of commercial buildings. Prior designs typically use at least two
fasteners, such as
a screw or a nail, which are inserted through openings in the sidewall of the
electrical box so that
the box can be attached to the stud.

1


CA 02578456 2007-02-14

[0041 The electrical box must be properly positioned in relation to the stud
itself and the outer
covering which is later placed over the stud. When the outer covering placed
on the stud is a
gypsum board material, the electrical box must be positioned so that it is
properly recessed
within the outer covering to allow for the electrical box to be accessed and
so that the front of the
electrical box is aligned with the surface of the outer covering. Prior art
electrical boxes that
attach directly to a stud are difficult to align and the front of the box
often does not align with the
outer wall covering. To facilitate the alignment of these electrical boxes, a
variety of different
brackets have been used. An electrical box is mounted in these brackets either
before or after the
bracket is attached to a stud. Typically, these brackets have special mounting
features designed
to facilitate the attachment of the bracket to a stud. However, many of these
brackets and their
mounting features are cumbersome and cannot be quickly and easily attached to
a stud.

[005] Accordingly, it is desirable to provide a mounting bracket for an
electrical box which
facilitates the attachment of the box to a stud. There is also a further need
for an electrical box
which assists the user in properly positioning the outlet for attachment so
that the electrical box
can be installed more easily and in a more cost efficient manner.

SUMMARY OF THE INVENTION

10061 In accordance with the present invention, a mounting bracket for an
electrical box is
provided. The mounting bracket includes: a base plate having substantially
planar top and
bottom surfaces, a first side, a second side, a first end, a second end, a
plurality of mounting

screw apertures and an opening for receiving an electrical box; a first flange
and a second flange
connected to the first and second sides, respectively, of the base plate,
wherein each flange has a
top and a bottom flange surface; a wall connected to the first end having
substantially flat inner
and outer wall surfaces, a central portion and a pair of opposing ends,
wherein the wall extends
from the bottom surface of the base plate; and a tab connected to each
opposing end of the wall,
wherein the tabs extend away from the wall and are substantially perpendicular
to the outer
surface of the wall.

[007) The plurality of mounting screw apertures are arranged to accommodate
electrical boxes
of different sizes and orientations and having different mounting tab
locations. The base plate

2


CA 02578456 2009-01-26

can also have a plurality of mounting slots which are used either alone or in
combination with
the plurality of mounting screw apertures to accommodate electrical boxes of
different sizes and
orientations and having different mounting tab locations.

[008] In a preferred embodiment, the top surfaces of the first and second
flanges are

substantially parallel to the top surface of the base plate. The first and
second flanges are
preferably connected to the first and second sides of the base plate by a
first flange neck and a
second flange neck, wherein the flange necks extend from the top surface of
the base plate. In
another embodiment, the opposing ends of the wall extend beyond the sides of
the base plate
and/or beyond the flange necks and also extend beyond the central portion to
define a notch in
the wall. In a preferred embodiment, instead of the notch, the wall has a wall
opening for
accessing the electrical box mounted in the bracket. Each of the flanges can
have one or more
flange mounting screw apertures for attaching the bracket to a stud using
mounting screws or
nails. In addition, each of the tabs can have one or more tab mounting screw
apertures for
attaching the bracket to a stud using mounting screws or nails.

[009] The mounting bracket can have a second wall or a stiffening member
connected to the
second end of the base plate to minimize bending or flexing of the base plate.
The second wall
is substantially the same as the wall connected to the first end of the base
plate and has a
substantially flat outer wall surface, a central portion, a pair of opposing
ends and a pair of tabs
connected to the opposing ends and perpendicular to the outer wall surface.
When a stiffening
member is used instead of a second wall, the distal ends extend beyond the
flange and/or the
sides of the base plate to a point that is substantially coplanar with the
tabs. When the bracket is
mounted to a stud, the tabs on one end of the two walls or the tab on one wall
and the distal end
of the stiffening member contact the side of the stud. Preferably, the second
wall or the

stiffening member extends from the bottom surface of the base plate and is
substantially parallel
to the wall on the first end of the bracket.

DETAILED DESCRIPTION OF THE INVENTION
[022] The present invention is a mounting bracket for an electrical box, which
is used to attach
the electrical box to a structure, typically a wall stud. The bracket includes
a base plate that has a
front surface with an opening for receiving the electrical box and a plurality
of apertures and/or
slots for securing the electrical box to the bracket using screws or other
fastening means. The
electrical box can be mounted in the bracket either before or after the
bracket is attached to a

4


CA 02578456 2007-02-14

structure. The bracket also includes a pair of flanges on either side of the
base plate, which are
used to attach the bracket to a structure. The flanges are connected to the
opposing sides of the
base plate by flange necks which, in this embodiment, extend upwardly and
outwardly from the
sides of the base plate, preferably at about a 45-degree angle. The flanges
are connected to the
flange necks so that the plane formed by the surfaces of the flanges is
parallel to, and also
preferably offset from, the plane formed by the front surface of the base
plate. The flanges have
mounting screw holes that are used to attach the bracket to a structure. The
bracket can also
have mounting screw holes in the flange necks that can extend to the base
plate and/or the face
of the flange. These holes allow screws or nails to be inserted into a wall
stud at an angle,
preferably about a 45-degree angle.

[023] The mounting bracket has a wall extending from at least one of the ends
of the base plate.
The wall has a pair of opposing ends and each end extends beyond the
corresponding flange
neck and bends outwardly, i.e., away from the base plate, to form a tab. The
tabs on the
opposing ends of the wall can have a mounting screw aperture that can be used
to secure the
bracket to a structure, preferable the side wall of a stud. When the bracket
is positioned on a
wall stud, one of the flanges contacts the front surface of the wall stud and
one of the tabs
contacts the side surface of the wall stud. Because the tabs extend beyond the
flange necks, the
flange necks do not contact the wall stud. The wall also has a notch in the
central portion that is
defined by the opposing ends. The notch provides clearance for cables and/or
wires that are
connected to the box.

[024] In those embodiments of the present invention in which a wall extends
from only one end
of the base plate, the other end of the base plate can have a stiffening
member, which extends
from the base plate in the same direction as the wall and which helps prevent
the base plate from
flexing. Preferably, the stiffening member extends along the entire end of the
base plate
(including the flange necks) and the surface of the stiffening member is
substantially parallel to
the surface of the wall on the other end of the base plate.

[025] FIG. 1 shows a front perspective view of a first embodiment of the
mounting bracket 10
used for an electrical box 90 (see FIG. 4). The bracket 10 includes a base
plate 12 with flanges
5


CA 02578456 2007-02-14

14, 16 connected to the opposing sides by flange necks 18, 20. The surfaces of
the flanges 14,
16 are parallel to, and also preferably offset from (but not necessarily), the
plane formed by the
surface of the base plate 12 and include a plurality of holes or apertures 24,
26 for securing the
bracket 10 to a structure, preferably a wall stud 80 (see FIG. 3). In this
fashion, either side of the
bracket 10 may be mounted to the stud. The surface of the base plate 12 is,
preferably, recessed
from the surfaces of the flanges 14, 16 so that the mounting surface of a
cover plate 92 (see FIG.
4) attached to the electrical box 90 will not extend beyond the surfaces of
the flanges 14, 16.
(026] The first embodiment of the bracket 10 also has a wa1130 which extends
from at least
one of the ends of the base plate 12. Its direction is opposite to the
preferred offset of flanges 14,
16 from bracket 10. The wa1130 has a pair of opposing ends 32, 34 which extend
beyond the
flange necks 18, 20. At the distal projection of ends 32, 34, there are a pair
of tabs 36, 38 which
are bent outwardly, away from the base plate 12 and which are substantially
perpendicular to the
wal130. The tabs 36, 38 have mounting screw holes 40, 42 for attaching the
bracket 10 to a stud
80 (see FIG. 3). In this embodiment, the wa1130 has a notch 31 that is defined
by the opposing

ends 32, 34. The notch 31 facilitates the entry of conduits and/or wires into
the electrical box 90
(FIG. 4). In those embodiments where a second wall (not shown) is provides,
the second wall is
connected to the second end of the base plate 12 and is substantially
identical to the first wall.
(0271 The base plate 12 for the first embodiment of the bracket 10 has an
opening 22 for
receiving an electrical box 90 (see FIG. 4) and a plurality of mounting screw
apertures 28,
preferably round holes, keyholes or slots, for securing different size
electrical boxes 90 to the
bracket 10. It should be noted that typical electrical boxes are either 4-inch
square boxes or 4-
11/16-inch square boxes. Each box size comes with mounting tabs whose spacing
and position
are industry specified. For the smaller 4-inch square box, the box itself can
be rotated 90 degrees
and yet the mounting tab locations will remain unchanged. This is not the case
for the larger 4-

11/16-inch box. If that box were rotated 90 degrees, the mounting tab
locations would be
different. Hence, as shown in FIG. 1, the center slot/keyhole 28 in each
corner of opening 22 is
provided for securing the smaller 4-inch box to bracket 10 regardless of
whether the box is
rotated 90 degrees or not. In contrast, the outer two slots/keyholes 28 in
base plate 12 are
provided for securing the larger 4-11/16-inch box to bracket 10, one set being
used when the box

6


CA 02578456 2007-02-14

is oriented one way and the other set being used when this larger box is
rotated 90 degrees.
Thus, with bracket 10, not only can multiple size boxes be attached thereto,
but the orientations
of these boxes can also vary and yet bracket 10 will still provide mounting
screw apertures 28
that will be properly aligned with the box's mounting tabs. The plurality of
mounting screw
apertures 28 provide means for mounting electrical boxes of different sizes
with different
mounting tab locations in a variety of different orientations.

[028] Different embodiments of the invention can have different size openings
22 to
accommodate a variety of different electrical boxes 90 having different
dimensions. The bracket
can also include one or more mounting holes 29 in the flange necks 18, 20 for
either securing
10 box 90 to bracket 10 or for securing the bracket 10 to a stud 80 (see FIG.
4) with either screws or
nails. These mounting holes 29 can encompass the base plate 12 and the flanges
14, 16.

[029] FIG. 2 shows a rear perspective view of the first embodiment of the
bracket 10 with a
stiffening member 44 extending from the base plate 12 on the opposing side of
the base plate 12
from the wall 30. The stiffening member 44 helps prevent the base plate 12
from twisting and/or
distorting when an electrical box 90 (FIG. 4) is mounted in the bracket 10.
Further, the distal
ends of stiffening member 44 extend beyond flange necks 18, 20. In a preferred
embodiment of
the invention, in place of the stiffening member 44, the bracket 10 has a
second wall (not shown)
connected to the second end of the base plate 12, which can be used to secure
the bracket 10 to a
structure and which further stiffens the base plate 12.

[030] FIG. 3 is a front peripheral view of the first embodiment of the
mounting bracket 10
attached to a wall stud 80. Due to its configuration, either side of bracket
10 could be mounted
so as to project from either side of stud 80. In FIG. 3, the flange 14 on one
side of the bracket 10
contacts the front 82 of the stud 80 and the tab 36 on the same side of the
bracket 10 contacts the
side 84 of the stud 80 while at the same time, the distal end of the
stiffening member 44 also
contacts side 84 of stud 80. Attaching the bracket 10 to two surfaces 82, 84
of the stud 80
securely holds the bracket 10 in place. Mounting holes 29 can also be used to
attach the bracket
10 to the stud 80. In the embodiment shown in FIG. 3, the mounting holes 29
extend across the
base plate 10, the flange neck 18 and the flange 14 so that, if desired, the
mounting screws or

CA 02578456 2007-02-14

nails can be inserted into the stud 80 at an angle. Further, as previously
noted, flange neck 18
does not contact stud 80, contact being made by flange 14, tab 36 and a distal
end of stiffening
member 44.

[031] FIG. 4 is a front peripheral view of the first embodiment of the
mounting bracket 10
attached to a stud 80 with an electrical box 90 installed in the bracket 10.
The flanges 14, 16 on
either side of the bracket 10 allow the box 90 to be mounted on either side of
the stud 80. Thus,
this assembly could be rotated 180 degrees so that the electrical box 90 is
inverted and flange 16
contacts the front 82 of the stud 80. This is especially useful when the
electrical box 90 is
factory installed in the bracket 10 and obviates the need to remove the
electrical box 90 and

reposition it in the bracket 10. FIG. 4 also shows a cover plate 92 on the
electrical box 90. After
the cover 92 is attached to the box 90, the surface of the cover is
approximately even with the
surfaces of the flanges 14, 16. The notch 31 in the wall 30 of the bracket 10
provides
unrestricted access to the apertures 94 in the electrical box 90.

10321 FIG. 5 is a side view of the first embodiment of the mounting bracket 10
positioned on a
wall stud 80. The flange 14 contacts the front 82 of the stud 80 and the tab
36 contacts the side
84 of the stud 80 while a distal end of stiffening member 44 also contacts
side 84 of stud 80 all
so as to securely attach the bracket to the stud 80. The opposing ends 32, 34
of the wall 30 and
the distal ends of stiffening member 44 extend beyond the flange necks 18, 20
so that flange
neck 18 does not contact the stud 80 when the flange 14, tab 36, and
stiffening member 44 are in
contact with the stud 80. FIG. 5 also illustrates the notch 31 in wall 30
which is defined by the
opposing ends 32, 34 of the wall 30. Tabs 36, 38 are substantially
perpendicular to wall 30 and
extend away from the base plate 12. When an electrical box 90 (FIG. 4) is
mounted in the
bracket, any force exerted on the base plate 12 is transferred to the stud 80
by the tab 36 and/or
flange 14 and/or stiffening member 44 so that the bracket 10 will maintain its
position.

[033] FIG. 6 shows a front perspective view of a second embodiment of the
mounting bracket
110 used for an electrical box 190 (see FIG. 9). The bracket 110 includes a
base plate 112 with
flanges 114, 116 connected to the opposing sides by flange necks 118, 120. The
surfaces of the
flanges 114, 116 are parallel to, and also preferably offset from (but not
necessarily), the plane
8


CA 02578456 2007-02-14

formed by the surface of the base plate 112 and include a plurality of holes
124, 126 for securing
the bracket 110 to a structure, preferably a wall stud 180 (see FIG. 8). In
this fashion, either side
of bracket 110 may be mounted to the stud. The surface of the base plate 112
is, preferably,
recessed from the surfaces of the flanges 114, 116 so that the mounting
surface of a cover plate
192 (see FIG. 9) attached to the electrical box 190 will not extend beyond the
surfaces of the
flanges 114, 116.

[034] The second embodiment of the bracket 110 also has a wall 130 which
extends from at
least one of the ends of the base plate 112. Its direction is opposite to the
preferred offset of
flanges 114, 116 from bracket 110. The wall 130 has a pair of opposing ends
132, 134 which
extend beyond the flange necks 118, 120. At the distal projection of ends 132,
134, there are a
pair of tabs 136, 138 which are bent outwardly, away from the base plate 112
and which are
substantially perpendicular to the wall 130. The tabs 136, 138 have mounting
screw holes or
apertures 140, 142 for attaching the bracket 110 to a structure, such as a
stud 180 (see FIG. 8).
In this embodiment, the wall 130 has an opening 131 which facilitates the
entry of conduits

and/or wires into the electrical box 190 (FIG. 9).

[035] The base plate 112 for the second embodiment of the bracket 110 has an
opening 122 for
receiving an electrical box 190 (see FIG. 9) and a plurality of mounting screw
apertures 128,
preferably keyholes or slots, for securing different size electrical boxes 190
to the bracket 110.
Different embodiments of the invention can have different size openings 122 to
accommodate a
variety of different electrical boxes 190 having different dimensions. The
bracket 110 can also
include one or more mounting holes or apertures 129 in the flange necks 118,
120 for either
securing box 190 to bracket 110 or for securing the bracket 110 to a stud 180
(see FIG. 9) with
either screws or nails. These mounting holes 129 can encompass to the base
plate 112 and the
flanges 114, 116.

[036] FIG. 7 shows a rear perspective view of the second embodiment of the
bracket 110 with a
stiffening member 144 extending from the base plate 112 on the opposing side
of the base plate
112 from the wall 130. The stiffening member 144 helps prevent the base plate
112 from
twisting and/or distorting when an electrical box 190 (FIG. 9) is mounted in
the bracket 110.

CA 02578456 2007-02-14

Further, the distal ends of stiffening member 144 extend beyond flange necks
118, 120. In a
preferred embodiment of the invention, in place of the stiffening member 144,
the bracket 110
has a second wall (not shown) connected to the second end of the base plate
112, which can be
used to secure the bracket 110 to a structure and which further stiffens the
base plate 112.

[037] FIG. 8 is a front peripheral view of the second embodiment of the
mounting bracket 110
attached to a wall stud 180. Due to its configuration, either side of bracket
110 could be
mounted so as to project from either side of stud 80. In FIG. 3, the flange
114 on one side of the
bracket 110 contacts the front 182 of the stud 180 and the tab 136 on the same
side of the bracket
110 contacts the side 184 of the stud 180 while at the same time the distal
end of the stiffening
member 144 also contacts side 184 of stud 180. Attaching the bracket 110 to
two surfaces 182,
184 of the stud 180 securely holds the bracket 110 in place. Mounting holes
129 can also be
used to attach the bracket I 10 to the stud 180. In the embodiment shown in
FIG. 8, the mounting
holes 129 extend across the base plate 110, the flange neck 118 and the flange
114 so that
mounting screws or nails can be inserted into the stud 180 at an angle if so
desired. Further,

flange neck 118 does not contact stud 180, contact being made by flange 114,
tab 136 and a
distal end of stiffening member 144.

[038] FIG. 9 is a front peripheral view of the second embodiment of the
mounting bracket 110
attached to a stud 180 with an electrical box 190 installed in the bracket
110. The flanges 114,
116 on either side of the bracket 110 allow the box 190 to be mounted on
either side of the stud
180, thus this assembly could be rotated 180 degrees so that the electrical
box 190 is inverted
and flange 116 contacts the front 182 of the stud 180. This is especially
useful when the
electrical box 190 is factory installed in the bracket 110 and obviates the
need to remove the
electrical box 90 and reposition it in the bracket 10. FIG. 9 also shows a
cover plate 192 on the
electrical box 110. After the cover 192 is attached to the box 190, the
surface of the cover is
approximately even with the surfaces of the flanges 114, 116. The opening 131
in the wall 130
of the bracket 110 provides unrestricted access to the apertures 194 in the
electrical box 190.
[039] FIG. 10 is a side view of the second embodiment of the mounting bracket
110 positioned
on a wall stud 180. The flange 114 contacts the front 182 of the stud 180 and
the tab 136



CA 02578456 2007-02-14

contacts the side 184 of the stud 180 while a distal end of stiffening member
144 also contacts
side 184 of stud 180 all so as to securely attach the bracket to the stud 180.
The opposing ends
132, 134 of the wall 130 and the distal ends of stiffening member 144 extend
beyond the flange
necks 118, 120 so that flange neck 118 does not contact the stud 180 when the
flange 114, tab

136, and stiffening member 144 are in contact with the stud 180. FIG. 10 also
illustrates the
opening 131 in the wall 130. Tabs 136, 138 are substantially perpendicular to
wall 130 and
extend away from the base plate 112. When an electrical box 190 (FIG. 9) is
mounted in the
bracket, any force exerted on the base plate 112 is transferred to the stud
180 by the tab 136
and/or flange 114 and/or stiffening member 144 so that the bracket 110 will
maintain its
position.

[040] Thus, while there have been described the preferred embodiments of the
present
invention, those skilled in the art will realize that other embodiments can be
made without
departing from the spirit of the invention, and it is intended to include all
such further
modifications and changes as come within the true scope of the claims set
forth herein.
